screws let you level and plumb without the need for shims when installing
door jambs, window frames, cabinets and panels. An 11/16 collar
section surrounds the head and rotates freely on the main shank. A two-piece
crown bit (sold separately) engages the collar and the screw simultaneously,
turning both until the collar seats flush. By removing the outer crown
portion of the bit, you can then turn the main Torx-drive screw shank
alone, to adjust for plumb or level.
Steel with zinc plating for corrosion resistance. Package of six includes
self-adhesive plastic covers to allow you to paint over the screw head.
